It now costs Ayan Hassan Abdirahman twice as much as it did just a few months ago to buy the wheat flour she uses to make breakfast each day for her 11 children in Somalia’s capital. Nearly all the wheat sold in Somalia comes from Ukraine and Russia, which have halted exports through the Black Sea since Moscow waged war on its neighbor on Feb. 24. The timing could not be worse: The U.N. has warned that an estimated 13 million people were facing severe hunger in the Horn of Africa region as a result of a persistent drought. Abdirahman has been trying to make do by substituting sorghum, another more readily available grain, in her flatbread. Inflation, though, means the price of the cooking oil she still needs to prepare it has skyrocketed too — a jar that once cost $16 is now selling for $45 in the markets of Mogadishu. “The cost of living is high nowadays, making it difficult for families even to afford flour and oil,” she says.

The U.N. World Food Program says food shortages could worsen when the lean season arrives in late summer.
